aye up rick , i believe that there are no changes to the 999s for 06 , mines an 05 , you get an asym termi with it , and for me its dog,s the danglies . basically the 05 s is the same engine as the 04 r minus some magnesium , probably 04 r owners will disagree
you could get an 04 r for the same money as a new 06 s its all down to preferance ,do you want new
